Finished:
Alone with You - okay game, but plays a little awkward
The Bard’s Tale IV - very nice party RPG with puzzles sprinkled in (some chests/rewards are very underwhelming, but fun overall)
Dead in Vinland - one part fun (exploring the island, events), two parts chore (management/resources)
Eliza - nice visual novel (fun solitaire variation, too)
GNOG - tiny, colourful… something?
The House of Da Vinci - plays similar to The Room series, but the quality is not there :(
Knightin+ - very fun tiny dungeon-crawler
Machinarium - Amanita nostalgia
Snowball! - snowy pinball game (quite small, btw)
Wonder Boy: The Dragon’s Trap - quite enjoyable (never played the original)
Planet Alpha - beautiful, simple platformer
